YOSC-ILLATING CUTTER FOR CARD-SETTING MACHINES.-

SBEGIFICATION forming part of Letters Patent No. 284,161, dated September {1, 1883.

Application filed March 29, 1883. (No model.) i i To all whom it may concern:

. Ocillating v of which the following is a specification.

simple and rapid ing or chippin Be it known that I, OLIVER ARNOLD, a citizen of the United States, residing at Worcester, of Worcester and State of Mas' in the county sachusetts, have invented a new and useful Cutter for Card-Setting Machines,

My invention relates to improvements in cutters forcard-setting machines, in which the cutters are made circular. The objects of my invention are,first, to afford facilities for sharpening and adjustment of the cutters," second, to obtain long wear and uniformity of the bevel of the cuttingedges and third, to avoid liability of breakg, which is peculiarly liable in the old form of cutters. I attain these objects by the mechanism illustrated in the accom-.

appear if removed from a wire between cuttingedges.

panying drawings, inwhich Figure 1 is a frontview of the cutters properly adjusted in. the block and attached to plate, Fig. 2, a viewof cutters asthey would block, and showing Fig. 3 is a top viewof pipes (or guide,) showing course of wire through clearance-ways to the cutters; Fig. 4, a view of a section of wire as it would appear after being cut,and showingthe chip detached 5 Fig. 5, an end view of cutters, showing open ing in pipe which guides the points of the wire to the cutters; and Fig. 6 shows cardclothing teeth set in leather.

Similar letters referto similar parts through out the several views.

forming a foundation trudes through block tachedthe oscillatinglever H, and held firmly to lever by set-screw i and draft-screw I,

drawing .cutter Fup snugly toiface of block 1 chance enough for lever H B B, but allowing the wire to the point of a perpendicular line between centers of cutters F and G. The second or'front part of guide is slotted lengthwise to admit the wire, and also grooved in three or moreplaces transversely for receptacles of dirt or scale, that would otherwise be liable to foul the slot and prevent the free passage of the wire. Through the pipes (or guide) KK the wire L is allowed topass to the cutters Fand G, where it is cutoff and pointed i V by a chip being taken out, thereby beveling.

in opposite directions both ends of a tooth.

(See Fig. 6.) In Fig. 4.is illustrated asection of wire cut off and the chip Mdetached. The dotted lines in Fig. 5 of cutter F and lever H showthe extent of the oscillation.

By removing cutters F and O the cuttingfaces may be readily ground and replaced, (being previously tempered,) and repeated until the circle be nearly completed.

I am aware that prior to my invention cutters have been in use that oscillate. I there: fore do not claimsuch a combination, broadly but What I do claim as my invention, and desire to secure by Letters Patent, is

A card-setting-machine cutter having circular cutters F and O, with stems insertedinto their sockets D and G, cutter 0 being held in place by binder-screws E E, and cutter F allowed to oscillate by lever H, substantially as described and set forth.
